A transformation achieving the optimal symmetric N-->M cloning of coherent states is presented. Its implementation requires only a phase-insensitive linear amplifier and a network of beam splitters. An experimental demonstration of this continuous-variable cloner should therefore be in the scope of current technology. The link between optimal quantum(More)
A study of the thermal properties of two-dimensional topological lattice models is presented. This work is relevant to assess the usefulness of these systems as a quantum memory. For our purposes, we use the topo-logical mutual information Itopo as a " topological order parameter ". For Abelian models, we show how Itopo depends on the thermal topological(More)
A recursive method for producing path-entangled states of light is presented. These states may find applications in quantum lithography and high-precision interfer-ometric measurements. The required resources are single-photon sources, linear optics components, and photodetectors. Adding a quantum memory greatly enhances the yield in comparison with the(More)
